An irritating iPhone user who endlessly tinkers on it. A worst case senario: somebody at a wedding who cuts in front of or hovers behind or puts their wide load arse in the way of a CONTRACTED photographer at a wedding.

Me: "I couldn't get the shot!!! Some iCunt got in the way!!!!" And as a result, photographer panics becuase some iCunt doesn't realise it's their JOB to take the freaking shots ...
